Hey! We have already analyzed all possible problems (and their solution) associated with connecting an iPhone or iPad to Wi-Fi -. But the fact is that in that article general problems were considered, and today I want to talk about one specific case. And this case, it should be noted, is very interesting.

So, recently I received a letter with a question of approximately the following content: “Good day! My iPhone lost its Wi-Fi connectivity this morning. The thing is that, having gone into the settings, I tried to turn on Wi-Fi, but nothing worked for me - the slider did not move. For some reason, it is shown in gray and cannot be activated. Please tell me what to do? "

But really, some strange "glitch" iOS - there is a Wi-Fi button, but it is not pressed. Or not a "glitch"? Let's figure it out, let's go!

In fact, the problem can be both software and hardware. And of course, first you need to exclude crashes in the iOS system. To do this, we perform the following actions:

  1. Hard reboot - it is done differently for different models ().
  2. We reset the network settings. To do this, open "Settings - General - Reset - Reset network settings".
  3. If there is a jailbreak, then. Since some of its tweaks can affect the performance of the Wi-Fi connection.
  4. Are you using beta firmware? Remember that from her - do it.
  5. Create a backup and restore the iPhone or iPad firmware via iTunes (to be sure,). See if the Wi-Fi icon is activated on a completely clean (without your data) device.

Did you do all these manipulations, but the problem persists? Unfortunately, in this case, the gray color of the button most likely indicates a malfunction of the Wi-Fi module.

By the way, this fact can indirectly confirm the impossibility of turning on Bluetooth - its icon will also be inactive.

How to find out more precisely? Open "Settings - General - About this device" and look at the line Wi-Fi address.

And now what to do - how to do the right thing?

  • ... If so, then feel free to take it to the warranty repair - let them figure it out themselves.
  • Is the service term over? Unfortunately, replacing and soldering a module is not the easiest operation - it cannot be done at home, without special skills and equipment. Therefore, you need to visit the service center. But there is good news - the cost of such a procedure is not very high. Although everything is learned in comparison….

And finally, I would like to note the following point.

On the Internet, as a way to deal with non-working Wi-Fi, you can find this advice - put it in the freezer or heat the device. Say, then the soldering will fall into place and everything will work.

I don’t know if you want to check this method or not, but we must remember about the disadvantages of such a solution:

  1. It rarely helps.
  2. The effect, as a rule, does not last long - after a while the Wi-Fi connection icon will turn gray and inactive again.
  3. You can easily overheat (overcool) the device and break something else - the motherboard, display, all kinds of controllers, modules, etc.

Therefore, in my opinion, this manipulation is an extremely dubious decision.

Although, if you are still going to throw out the device (since you simply don’t need it with a disabled Wi-Fi button), then you can try. But only at your own peril and risk, because the consequences can be unpredictable. Again, a visit to a service center would be much more correct.

P.S. After reading the article, did it become even a little clearer? Like it, click on the social media buttons, get + 50% to the strength of the Wi-Fi signal!

P.S.S. You still have questions, do you want to share a problem or some alternative solution? Welcome to comments!

Now we will analyze the main reasons why your iPhone does not see or does not catch WiFi and how to proceed in this situation.

This article applies to all iPhone 11 / Xs (r) / X / 8/7/6 and Plus models on iOS 13. Older versions may have different or missing menu items and hardware support specified in the article.

Top reasons why there is no WiFi on iPhone

There are the following reasons why Wi-Fi stops working on iPhone:

  • Incorrect router / modem settings.
  • Prohibited public network.
  • Hidden network.
  • The iPhone does not have WiFi enabled.
  • You pressed the button "Forget the network for a day" earlier.
  • IOS software crash.
  • Accidental reset of network connection settings.
  • Hardware breakdown of the phone and failure of the module.

Signs of a Wi-Fi problem

It's easy enough to understand that there are problems in the work of Wi-Fi. If Wi-Fi is slow, the problem might be with your router, not your iPhone. Therefore, first you need to check the correctness of the modem settings.

Ask your question to a specialist

Do not know how to solve a problem in the operation of your gadget and need expert advice?

The following signs indicate a Wi-Fi malfunction:

  • The device does not connect to the access point.
  • The smartphone does not catch the network.
  • Wi-Fi freezes after a short period of time.
  • The Wi-Fi icon is missing from the top bar.
  • Low internet speed.
  • The Wi-Fi connection button does not turn on.
  • Lost network settings.

In the production of Apple equipment, it undergoes rather stringent testing, but some users note that even a new iPhone may not catch Wi-Fi. It is much easier to troubleshoot a software failure than a hardware failure. In any situation, the way to eliminate a breakdown depends on its complexity and type.

Problems with a router or public network

It is Apple's policy that you will never be able to connect to a network if its settings are weak from hacking from third parties. Those. this is a kind of protection of the phone from getting your data by "hackers" the moment you connect to such a weakly secured network.

You can often find such networks in cafes, shops, train stations and other crowded places. If the network has normal protection, then you will connect without any problems.

And if you can't catch WiFi at home, or in some trusted place (work, with a friend, etc.), then most likely the matter is in setting up the router (it does not allocate IP, there is a limit on connections and other settings that depend on the router manufacturer).

IOS update

An outdated version of iOS may make the wireless network unstable. To check your gadget for available updates, you need to go to "Settings", select "General", then click on the "Software update" section.

This method of updating implies that the download of the new firmware version will be carried out “over the air”. You will need a working Internet connection (for example, with a 4G network if Wi-Fi is not available).

Users can also update the firmware using iTunes:

  • We connect the iPhone to the computer.
  • All basic information (firmware version, phone number, model, etc.) will be displayed in the "Overview" section of Aityuns about the gadget.
  • To check for updates and install them, you must click on the "Update" button.

This method should be used in a situation where recently the Wi-Fi network gadget finds and connects to them, but the speed of the connection itself is very low.

Resetting Wi-Fi network settings

Quite often, Wi-Fi does not work due to incorrect settings. Reset required:


Settings - Privacy - Geolocation services - System services (located at the end of the list) - Turn off WiFi opposite and reboot.

In a situation when the Wi-Fi network does not work on the iPhone, and the networks themselves are not displayed in the list of available access points, or when the smartphone is connected to the network, but not a single page on the Internet is loaded, you should reset the iPhone settings - Hard Reset. After that, all information from the gadget will be deleted, so you need to execute.

With every new major update to iOS or even macOS, some users are experiencing quite serious problems. iOS 10 is no exception in this regard. Many users started to complain about the problem with the Wi-Fi network. There are several ways to solve the problem.

Reboot the router

Sounds simple enough, but sometimes the problem isn't mobile or iOS. First, you need to make sure that the router itself is working properly.

Hardware reboot of the iOS device

If rebooting the router did not help, the next logical solution would be to hard reboot the iPhone or iPad itself. To do this, you need to hold down the Power and Home buttons (or the volume button on the iPhone 7) for 10-15 seconds until the Apple logo appears on the screen.

Reconnecting to a Wi-Fi network

An unstable Wi-Fi connection does not always mean a hardware or software malfunction, sometimes it can just be a failure of a specific connection to a specific network. In order to fix it, go to the Wi-Fi settings and click on the "i" icon next to the desired Wi-Fi network, then select "Forget this network". Now try to reconnect to the network.

Reset network settings

In many cases, resetting network settings helps. Go to Settings -> General -> Reset -> Reset Network Settings. This procedure does not affect user data, but removes all network connections.

Wi-Fi Assistance

Wi-Fi Assist is an interesting and relatively new feature in iOS. It is not unique to iOS 10, but it does affect Wi-Fi performance. The meaning of the "Wi-Fi Assist" function is the ability to compare the bandwidth of the Internet connection over Wi-Fi and over a mobile network. In the event that the wireless network is not stable and fast enough, the mobile device is able to independently switch to using the mobile Internet - 3G or LTE. To disable the function, go to Settings -> Cellular.

Disable Location Services for Wi-Fi

Another feature that directly affects the Wi-Fi connection. To turn off location services for Wi-Fi networks, go to Settings -> Privacy -> Location Services -> System Services, use the slider to deactivate location services for Wi-Fi networks and restart your device.

Clean install of iOS 10

If none of the above helps, it's time to move on to more radical methods. To perform a so-called "clean" installation, you need to update iTunes for Mac or Windows to the latest version and download the iOS 10 IPSW firmware file for your device.

Now turn off Find My iPhone in Settings-> iCloud -> Find My iPhone. Connect your iOS device to your computer and select it in iTunes. Hold down the Alt key on Mac and Shift on Windows, select the "Restore" option and specify the path to the downloaded IPSW file.

Wait for the device to boot and restore your data from the backup.

Rollback on iOS 9

Even if installing iOS 10 from scratch didn't change anything, it might be worth rolling back to the previous version of the OS.

To get started, download the iOS 9 firmware IPSW file for your device. Then turn off Find My iPhone in Settings-> iCloud -> Find My iPhone.
Connect your iOS device to your computer and put it into DFU mode. In iTunes, hold down the Alt key on Mac and Shift on Windows, select the "Restore" option and specify the path to the downloaded IPSW file.

Do not disconnect the gadget from your computer until iTunes notifies you of success.
